Long story short... at work (school district) we have a full blown Windows network. () I however have a spare computer set up that runs Ubuntu so I can use various utilities on it.
We found a student who was instant messaging. *tisk tisk* and we have their IP. We ran ping -a on the IP but it didn't pull the host name as it should.
Using Ubuntu Intrepid, is there any way I can dig up the host name from the IP that I have?
